ITE Products : English : EB-2000 : EB-116 Position Control and Stepper Motor

EB-116 Position Control and Stepper Motor EB-116 Position Control and Stepper Motor

The EB-116 is a single hoard comprehensive instructional module designed to teach basic concepts of position sensors to technology students. The module can be operated as a stand-alone unit or integrated to the newly developed EB-2000 Computer Managed Laboratory.

The module contains experimental circuits with which the student performs a number of conceptual experiments at various levels of difficulty. Manual or computer driver fault-finding exercises and testing are available when the module is interconnected to the SB- 2000 sys tern, providing valuable experience in the training and diagnosis of faults. Test equipment, when used, attaches to the board via 2mm jacks, placed at various points around the circuits. Students are required to do only a minimal amount of wiring so training time is maximised. A comprehensive student manual is provided with each training module. The manua1 correlates to the exercises to convey concepts relating to the technologies covered, allowing focus on specific performance objectives.

Description

The EB-116 module is designed so students will spend the maximum time on the experiments and practice drills for testing comprehension and troubleshooting. The module also ensures that students use their time more efficiently. The printed circuit boards are pre-wired so that set-up time is minimal. For operation the module is connected to a PUZ-2000. To facilitate the exercises, all the major signals are brought out on-board with 2mm jacks for tests and interconnections. The ICs and the transistors are mounted on sockets, enabling easy replacement. The student has only to plug-in the appropriate patching cords and shorting plugs in order to perform the recommended experiments. The boards also come equipped with "black boxes" containing components used in the fault-finding and practice modes, components which should not be visually identified by the trainee.
